for use.

gotten at and the repair made no matter at what point this tear or break may take place My object is to provide a simple practical machine which shall be cheap to manufacture, easy to operate, and which shall be adapted to fold and interlock a multitude of ribbons or webs of paper simultaneously, which shall be especially adaptedto handle cigarette, toilet, and like tissue papers, which are notoriously flimsy and are so liable to tear, but which machine is so constituted that if any single web or any number of webs break the ,torn or broken web can be quickly in the machine.

.. The invention consists of the parts and the jconstruction and combination-of parts, as

hereinafter more fully described and claimed,

' having reference to the accompanying draws, in which,-

igure' 1 is a plan view of the machine.

Fig. 2 shows folding-dies in relative position..

Fig. 3 is a section through the dies. Fig. 4 is a section of the feed end, and Fig. 5 is a diaammatical representation of the intereaved papers.

In the practice of my invention I employ a die member, as A, which is made of a strip of suitable sheet metal or heavy Manila paper or like stiff bendable material. This strip is bent over along both edges to form the lateral flanges 2, which inclose suitable troughs or guidechannels for the strip of paper 3. These guide-flanges are connected at suitable intervals by the'cross-straps 4. These crossstraps may be one inch, more or less, inwidth.

At each end of the die, where the paper enters and leaves themold, the connecting-strap may be'two'or three inches, more or less, in width.

The strip A is flat at the feed and and is bent centrally and longitudinally toward the delivering end, so as to bring the flanges 2 epposite each other until the sides of the bent strip adjacent the delivery end stand nearly parallel, the die being substantially V- shaped or A-shaped in cross-section along its bent portions and the V or A narrowing as the discharge end of the die is approached. The cross-strips are uniformly parallel with that portion of the strip A which they are directly opposite to. The result of this .construction is that when a strip of paper or Web is drawn through the die from the flattened end to the folded end of the die the web is folded lengthwise and centrally. the edges of the paper running in the grooves formed by the turned-over flanges and the paper being held in place by the cross-straps 4. By thus making an open-work die of tubular form friction on the tissue web is very greatly reduced. If a closed die of tubularforni is used,- the friction is often so great that the delicate web or paper is being broken continually, and it is a source of great annoyance and inconvenience to get the web started again.

By constructing the die in the form here shown and placing the cross-straps 4 at such intervals as {will just keep the paper straight and properly guided it is an extremely sim 'le I matter-to get at the broken web and men it or else draw it through, so that the creasing operations may continue.

In the actual machine as constructed by me I use a lower series of die members A, ar-

ranged with their edges in upturned position and with the narrower ends of the dies all pointing in one direction. On top of thiss'eries of upturned or V.-shape dies and overlapping the same in break-joint fashion I place oosely a second series of molds, the bent'go sides of this upper series pointing downward and fitting into the corresponding depressions in the other series. There may be any desired number of these dies used in a single machine. own Web of paper, and all t e webs are adapted to be drawn through all the 'dies at the same time by any suitable means, such as friction-rollers 5.

Any suitable form of support may be prO- roof vided for the dies, and preferably the latter are mounted loose on the other, so that any one of the upper series of dies may be %uickly lifted up in order to efiecta repair in a roken Each die is ada ted to receive its 5 web in case a break or tear occurs. This ready inspection of the web while in the die is an advantage not possessed by any machine of which I have knowledge-and is of utmost practical importance. Moreover, by reason of the triflin amount of friction offered tears and breaks in the webs are of less frequent occurrence than would be the case witha die of closed tubular form.

It is readily understood that the upper and lower arrangement of the dies, tapered and intermes'hed as they are,resu1ts in the several webs of paper being interleaved and interlocked the moment they emerge from the dies. These interfolded webs are then cut into suitable lengths and put up in suitable packages. There may be from fifty to one thousand of these interfolded leaves in one package, and the package would have a convenient central slot through which a top leaf rojects. By pulling on this projecting leaf 1t operates to partly withdraw a second leaf, so that each-leaf maybe withdrawn singly.

It should bev statedthat the dies of the two series differ in this respect, that the lowermost dies, or those of V shape in cross-section, having their under sides closed and their upper or reentrant portions open, while the dies of the 'upper. series, or those of A shape, having their upper exposed convex sides made op'en-workthat is, the cross-straps of the lower series of dies are V shape or concave and the cross-straps of the upper s eries are A shape or convex, and the cross-stra s in both series are always toward-the top. he result is that the webs of paper in the upper series are always in sight=throughout the major portion of the length of the-dies, and any'repair to the upper webs'can-be made without disturbing-the dies. At the same time if a web of anyparticular lower die becomes broken or torn it only-requires the lifting up of one or two of the corres onding upper dies in order to ex ose the bro en part.

It 1s manifest that I may bend the lower die-t0 have its open-work side downward,

' just as the upper die is.

Having thus described my invention, what I claim, and desire to secure by-Letters Patent,'is

1. A paper-folding machine comprising upper and lower series of dies, each die in each series comprising a strip of stiff, bendable material having its longer edges bent to form lateral guide-flanges for the web, said flanges connected at intervals by narrow cross-straps and said strip bent longitudinally and centrally with one end of the die formed by said strip and straps substantially flat and the other end-with its sides substantiallyparallel, the bent'sides of the dies in one series fitting'into the corresponding depressions in the other series.

convexed relative to the 2. In apaper-folding machine, a die formed from a strip of suitable bendable material,

the edges of said strip overturned to form lat eral guide-flanges, said flanges connected at intervals by cross pieces or straps, said strip flattened at its feed end and bent centrally and longitudinally toward the other end, said cross-straps being maintained parallel with the adjacent surface of said strip, said bent strip and cross-pieces operating gradually to fold a web of paper centrally and longitudinally when the web is passed therethrough,

and a second die corresponding to the first one and having its bent sides fitting into the corresponding depression of said first die, said cross-strips of the dies affording ready access to the web at any'point in'the lengths 8c of the dies.

3. In a paper-folding machine, the combination of an upper and a lower series of dies, each die in each series comprising a strip of suitable bendable material having lateral 8 5 ward the delivery end of the die, the dies of go the lower series being substantially concaved and the dies of the upper series substantially dies of said lower series, with the bent sides of the upper series fitting the concavities of the lower series, said 9 5 cross-straps of both series of dies being uppermost whereby the Web in each die is viewable from the top and for a major portion of the length of the die.

4. In a paper-folding machine, the combination of an upper and a lower series of 0 enwork dies of tubular form, the dies of eac series being bent lengthwise so as to operate gradually to fold a web of paper centrally and longitudinally when a web is assed therethrough, the dies of the lower series being substantially concaved and the dies of the upper series being substantially convexed in cross-section relative to the dies of said lower series, the sides of the dies of the upper series fitting the concavities of the lower series, and the open-work part of each die being uppermost so that the web in each die is viewable from the top for the major portion of the length of the die.

5. In a paper-folding machine, the combination of an upper and a lower series of 0 enwork dies of tubular form, the dies of eac series being bent lengthwise so as to operate gradually to fold a web of paper centrally and longitudinally when the web is assed therethrough, the dies of the lower series being'substantially concaved and the dies of the upper series being substantially convexed in cross-section relative to the dies of said lower series, the sides of the dies of the upper In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
